==Definition==
'''FLOAT''' sin ( <'''FLOAT''' angle> )

Returns the sine of the specified [[angle]].

This [[function]] performs a sine calculation on the specified angle and returns the value as a [[floating point]] number between -1 and 1.

== Parameters ==
{|
| '''FLOAT''' angle || - [[Angle]], in thousandths of degrees. i.e. 75000 = 75º
|}

== Returns ==
'''FLOAT''' : The sine result of the specified [[angle]].

== Notes ==
The [[angle]] value used in this function should be in thousandths of degrees, as most angles within [[Fenix]] are, and will return a [[floating point]] value between -1 and 1.
